Y(ci. azz- 1574) The invention relates generally 'to metallic receptacles and ,primarily seeks `to provide a novel pouring spout or nozzle mounting and a novel method of forming the same.

It is, of course, quite common to provide metallic receptacles with spout structures through which liquids can be poured, and such structures usually have a portion eX- tended through and secured in a circular mounting in a `portion of the receptacle and also include a threaded portion presented externally of the .receptacle and upon which a suitable closure is threadably mountable and removable. Torsional strains imposed upon the spout structures incidental to the threading on or olf of the spout closures tend to loosen the spouts in their mountings and cause leakage. Solder bonding or similar unions, or the employment of complicated structures and sealingrneans have been resorted to in order to prevent this provision of leaky spout mountings, but such complicated structures have been found unsatisfactory for economic reasons, and diculty has been experienced Vin providing satisfactory solder bonds when the metallic receptacles and spout structures have been formed of black iron. It is, therefore, a purpose of the present invention to provide a novel spout mounting structure which is simple and inexpensive and capable of providing the desired seal without danger of turning during threading Von or off of a closure, and without resorting to solder bonding. lt is also a purpose of the invention to -provide -a novel method o'f mounting such spout structures.

An `object of the invention is to providea novel method of forming a spout mounting .of the character stated which comprises, providing a spout mounting wall with acircular receiving opening surroundedbya frusto-conical wall portion, providing a spout with a cylindrical neck portion d'imensioned to snugly fit the opening and inserting the .neck in the opening, flattening an annulus of the irusto- I coniform wall portion immediately about the opening to cause the opening defining edge to be constricted and firmly grip the spout neck portion, and reshaping the spout to provide opposing seam portions at opposite sides of the flattened wall annulus and gripping the saine to secure the mounting of the spout.

Another object of the invention is to provide a method of the character stated which includes placing the frustoconical wall portion with relation to the direction of projection of the spout so as to provide a depression surrounding the spout, and applying a sealing media in the depression.

v Another object of the invention is to provide `a method of the character stated which includes the steps of providing outward protuberauces on the spout neck and causing them to be indented inthe edge ofthe neck receiving opening so as to prevent turning of the spout in the opening.

Another object of the invention is to provide a method of the lcharacter stated which includes the step of reshaping the spout mounting seam to provide interlocking irreg- 2,889,968 Patented June 9, 1959 ularities therein effective to prevent rotation of -thespout in the opening.

Another object of the invention is to provide a method of the character stated wherein the reshaping of the spout at one side of the gripped wall annulus is effected in the form of a two walled outwardly directed annular fold and the reshaping of the spout at the other side of ysaid annulus is by Way of bending the spout neck extremity outwardly against said annulus.

Another vobject of the invention is to provide amethod of the character stated wherein thereshaping of the/spout and the flattening of the annulusof the frusto-coniform wall portion are simultaneously effected.

Another object of the invention is to provide a spout mounting of the character described comprising, a mounting wall havinga-circular opening therein, a spout having a cylindrical neck portion .mounted in the opening and of a size for snugly tting therein, the Wall having an annulus immediately surrounding the spout neck -attened from an initial truste-conical shape so that the opening has been constricted to firmly grip the spout -neck surrounded thereby, and the spout having an outwardly directed ange portion at each side of the spout neck gripping wall annulus and gripping said annulus between them to form a mounting seam.

Another object of the invention is to provide a spout mounting of the character described wherein the flattened wall annulus is offset inwardly from the surrounding portion of the mounting wall to provide a depression surrounding the spout mounting seam, and there being included fa seam sealing media in the depression yand sweated into the seam.

Another object of the invention .is to provide a lspout mounting of the character stated wherein a novel mechanical interlocking-of parts is provided .for lin the mounting seam structure, the same -being effective to prevent rotation of the spout in the mounting opening.

A further object of :the invention is to provide a spout mounting of the character described wherein the spout flange portion at one side of the gripped wall annulus .is in the form of a two walled outwardly directed .annular fold and the spout flange portion at the other side of the gripped wall annulus is in the formof a single outwardly directed kannular flange.

A still further object of the yinvention is to provide a spout mounting of the character described wherein the spout neck is of double thickness V'formed lby folding the end extremity back upon itself, the spout flange portion at the `inner side of the gripped wall annulus is in the form of a two walled outwardly directed fold, and the spout flange portion at the outer side of the gripped wall annulus is in the form of a single flange ydirected outwardly from the portion of the -neck folded back up'on itself.

With the above land other objects in view that will hereinafter appear, the nature of the invention will be more fully understood by following the detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the drawings:

Figure l is a fragmentary sectional view illustrating a nozzle placed in a can body wall opening preparatory to the completion of the mounting.

Figure 2 is a fragmentary sectional View illustrating an optional manner of shaping the nozzle preparatory to the placing thereof in the receiving opening in which it is to be secured.

Figure 3 is a fragmentary sectional view illustrating the complete mounting of the spout of Figures y'l andl.

Figure 4 is a fragmentary inverted plan view illustrating a modied form of spout placed in its receiving opening in the manner shown in Figure 1.

Figure 5 is a View similar to Figure 4 showing the breast area surrounding the spout receiving opening flattened to cause the opening dening edge to becontracted and indented by the protuberances provided on the neck of the spout, thereby to prevent rotation of the spout in the opening.

Figure 6 is a View similar to Figure 3 illustrating a modified arrangement in which the seam structure by which the spout is secured to the breast edge deiining the spout receiving opening is deformed to a wavy shape assuring against relative rotation between the spout and breast members.

Figure 7 is a fragmentary inverted plan view illustrating the spout mounting of Figure 6.

Figure 8 is a view similar to Figure 2 illustrating another modification of the spout mounting, the initial insertion of the spout in the mounting opening being shown.

Figure 9 is a fragmentary sectional view illustrating the completion of the spout mounting seam of Figure 8.

In the example illustration of the invention in Figures 1 to 3 a can body is indicated at 5 as having a breast 6 secured thereon by a conventional seam 7. The breast is provided with an annular frusto-conical depression 8 having a spout neck receiving opening 9 at the center thereof. The spout generally designated 10 includes a vthreaded main body portion 11 having an outwardly directed bead 12 for resting on the depressed annulus about the opening 9 therein in the manner clearly illustrated in Figure l. The bead 12 merges into a downwardly directed cylindrical neck 13 dimensioned to -closely t within the breast opening 9.

In the completion of the mounting of the spout the breast depression is flattened as at 14 to provide a horizontal annulus 15 and contract the edge defining the opening 9 into tight gripping contact with the spout neck 13. Either simultaneously with the flattening of the depression portion or annulus 15, or subsequently thereto, the bead 12 is attened or folded as at 16, and the neck 13 is bent outwardly iiat against the annulus 15 as at 17, thus providing a double fold seam portion above the annulus 15 and a single thickness seam portion below said annulus with the dat annulus rmly gripped between said seam portions.

The mounting described hereinabove is particularly effective when container structures are being formed of black plate. It is well known that it is difhcult to solder bond black plate without very careful preparation with a proper ux, or in other words with very careful removal of any oxidation or scale. Of course, if the mounting is formed of tinned metal, an efficient solder bonding can be effected with facility. When the mounting is formed of black plate, however, a proper hermetic sealing of the spout mounting can be eected by applying a melted plastic sealing material, as indicated at 18 in Figure 3, the bond being sweated into the seam in the usual manner. In other words, it is to be understood that the bond indicated at 18 in Figure 3 may be formed of a plastic sealing material, or it may be a solder bond according to desire and the nature of the metal of which the mounting is formed.

Figure 2 illustrates a slight modification in which the bead 12 is flattened or folded at 19 before the nozzle neck is inserted through the breast opening. It is to be understood that the other steps in the vformation of the mounting can proceed in the manner previously described.

' In Figures 4 and 5 another slight modication of the mounting is illustrated wherein the spout neck 20 is provided with upright protuberances or ribs 21 equi-distantly spaced thereabove in the manner clearly illustrated in said gures. The protuberances or ribs are dimensioned to snugly engage within the mounting opening 22 in the 'usto-coniform depression 23 in the breast upon initial insertion, and then upon the flattening of the depression portion in the manner previously described, the ribs will be indented at 24 in the mounting opening defining edge, thereby to assure against rotation of the spout within said opening. It is to be understood that rib receiving recesses could be preformed in the mounting opening edge 22 should this be desired. In this instance it would not be necessary to form the rib receiving recesses by pressure application and the attening of the frusto-conical annulus would serve to bring the neck opening dening edge into tight gripping contact with the spout neck and all of the protuberances or ribs thereof.

In Figures 6 and 7 of the drawings an additional slight modication is illustrated, and according to this modiiication the seam structure formed in the manner previously described is rolled or pressed between suitable shaping tools to displace the seam plies out of plane and form a wavy seam as at 25. This waving of the seam structure would serve a purpose similar to that of the protuberances or ribs 21 in preventing rotation of the spout within the mounting opening.

An additional modification is illustrated in Figures 8 and 9, and according to this modification the breast 26 includes the usual frusto-conical depression 27 having the spout receiving opening 28 therein, but the spout 29 has its lower extremity or neck turned outwardly upon itself at 30, and then into an outwardly directly horizontal flange 31. In completing the mounting the depression annulus 32 is flattened in the manner previously described and then the double thickness lower neck extremity is folded outwardly and upwardly over the opening defining edge to complete the seam in the manner clearly illustrated in Figure 9.

It is to be understood that all of the mounting structures described herein can be bonded by a plastic or other sealing media in the manner described in the rst disclosed form of the invention.

While example spout mounting structures, mounting steps and step sequences are disclosed in detail herein, it is to be understood that such structures, steps and Ysequences are subject to variations without departing from the spirit and scope of the invention as dened in the appended claims.
